"In order to continue, You need to update the console" loop

Hello there,

Ive seen already posts about this problem around here but nothing seems to be working so Im starting to get desperate.

My switch was fine a few months ago, I tried and use it yesterday only to find myself blocked by the software on whatever I tried to do.

I saw on this sub that connecting to a phone hotspot could help...but the console says its impossible to retrieve the IP address of any WiFi I tried.

Next I tried the maintenance screen, trying to update, to restart the console while keeping games saves files, to update and exit.

NOTHING.

PLEASE SAVE ME (also please excuse any mistakes in my writing, Im French QwQ)
